What’s a gamertag?

It’s your online alter ego for Xbox. Your gamertag represents you when you’re playing games and sharing with other people in the Xbox community. We’ll create a gamertag for you the first time you sign in to Xbox. If you don’t like it, you can change it once for free.

To change your gamertag on your PC, open the Xbox app and select your gamerpic to open your profile. Then go to Customise > Change gamertag and follow the instructions.
